Hey, I noticed this template and wanted to use it, but I noticed that it’s incompatible with the categorization logic the extension template uses. The latter just checks for a few keywords to decide on the categorization without providing an actually clean output (e.g. if I choose “GPL” in the infobox, it will correctly categorize it but only show “GPL” in the output). When using this template, it will show a nice link and full name of the license, and also provide a license category for the extension, but then the standard default categorization mechanism of the extension template kicks in and also adds it to Category:Extensions with unknown license.
Were there any plans to integrate this template into the extension template so that only one of it will do the categorization?
